SPECIFICATION forming part of Letters Patent No. 765,833, dated July 26, 1904:.

Application filed December 18, 1903. Serial 'No. 185,612. (No model.)

To all wilwnc it may m-nne Be it known that I, WVILLIAM E. HAMILTON, a citizen of the United States, of the city of Zanesville, county of Muskingum, and State of Ohio, have invented a new and useful Improvement in Locomotive Oar Pullers, of which the following is a specification.

My invention relates to mining machinery, and has for its principal objects to provide a transportable machine for handling mine-cars, to move mine-cars back and forth from the cross-entries of mines to the chamber thereof, to provide a car-puller that may be associated with a loading-machine, to provide a self-propelling or locomotive car-puller, and other objects hereinafter more fully appearing.

My invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specifieation,and wherein like symbols refer to like parts wherever they occur, Figure 1 is a diagrammatic View of my improved car-puller, showing it applied to the tail-rope system of cable propulsion. Fig. 2 is a plan view of my improved car-puller, only a portion of the truck being shown. Fig. 3 is a side view of the parts shown in Fig. 2. Fig. 4 is ahorizontal section through the cable-drums and associated parts. Fig. 5 is a side view of the anchor-clamp on an enlarged scale, and Fig. 6 is a rear view of the anchor-clamp.

1n the usual plan of mines, especially coalmines, a track 1 is laid in the cross-entry and a track 2 in the mine-chamber, the two tracks being connected by a switch and curve 3. A block 4, provided with one pulley, is secured .near the center of the track 1 in the crossentry. A second block 5, having two pulleys, is mounted substantially at the center of the curve 3; A rope or cable 6 runs over one pulley in the block 5, around the pulley in the block 4, and then over the other pulley in the block 5, the ends of the cable being connected to separate winding-drums. Intermediate its ends the cable 6 is provided with a hook 7, that is adapted to engage an eye 8 on the car.

The cars are thus connected to the cable, so

as to be moved in either direction.

The cable-driving mechanism is .preferably mounted upon a self-propelling truck 9. A motor 10 of any desired type is mounted on the truck. Upon the end of the main shaft 11 of the motor a gear 12 is fixed, which 'meshes with a gear 13, fixed upon a shaft 14.

A gear 15 is fixed upon the end of the latter shaft and meshes with a gear 16, connected to a clutch 17. This clutch 17, hereinafter called the primary clutch, is mounted upon a shaft 18, which it connects with the gear 16. A lever 19 is provided to manipulate the primary clutch 17, A bevel-gear 20, hereinafter called the primary bevel-gear, is fixed upon the shaft 18.

A hollow shaft 21 is journaled in bearings 22 23 on the truck. Bevel-gears 24 25, hereinafter called secondary bevel-gears, are loosely mounted on said hollow shaft in position to mesh with the primary bevel-gear 20. They are held in position by collars 26 27 28 29, fixed upon the shaft 21 by screws. Thus the primary bevel-gear may be allowed to run continuously without turning the shaft 21. The opposite faces of the secondary bevelgears are provided with clutch-teeth 3O 31 32 33. The secondary bevel-gears are thus combined clutch members and bevel-gears. It will be observed that the secondary bevelgears rotate in opposite directions.

A clutch member 34, having clutch-teeth 35 36 on its opposite faces, is mounted on the shaft 21 between the secondary bevel-gears. It is longitudinally movable on said shaft, but is secured against rotation thereon by a feather 37. The clutch member is provided with a circumferential groove in which a collar 38 is located. A shifting-lever 39 is mounted on a bracket 40 and is provided with a slot 41, with which a pin 42 on the said collar 38 engages. By this means the clutch member may be moved either to right or left and brought into engagement with either of the secondary bevel-gears, and thus rotation of the shaft 21 in either direction may be produced.

A driving-sprocket 43 is fixed upon one end of the shaft beyond the bearing 22, a driven sprocket 44 is fixed upon one axle of the truck, and a sprocket chain 45 connects the two sprockets. As the driving-sprocket may rotate in either direction with its shaft, it follows that the truck may be propelled either forward or backward.

W inding-drums 46 47 are loosely mounted on the shaft upon opposite sides of the secondary bevel-gears. These drums are alike. Each has a flange 48, provided with clutchteeth 49 on the face adjacent its respective secondary bevel-gear. The hub of the drum is recessed to provide a chamber 50 fora lubricant and to reduce the area of contact with the shaft. At the end each drum is provided with a recess 51, concentric with the shaft 21 and closed by a plate 52. In the groove thus formed is a ring 53, which has apin 54 therein projecting through oppositely-located slots 55 in the shaft. A shifting-rod 56 extends through the shaft and is connected with said pins 54 54. At one end the shifting-rod hasagrooved cylindrical enlargement 57, which may be integral therewith or secured thereon. Asplit ring 58 engages the groove and is provided with a pin 59. A shifting-lever 60 is pivoted on a bracket 61 and has a slot 62 in position to be engaged by said pin 59. By the operation of the said shifting-lever 60 either drum may be connected to its respective secondary bevel-gear, and their connection is such that when one drum is connected the other is disconnected.

Means for braking the drums are provided. Each drum is provided with a grooved flange 63 at its outer end. A. brake-belt 64, having blocks 65 of complementary shape, engages the groove. A rock-shaft 66, journaled in bearings 67 68 on the truck, bears transverse arms 69 70, secured thereto at their centers. The ends of the brake-belts 64 64 are connected to the arms 69 70, respectively. The transverse arms are set at an angle to each other, so that by moving the handle-lever 71 upwardly the brake will be set upon one drum and by moving it downwardly the brake will be set upon the other drum.

hen the car-puller is located in position, it is desirable to anchor it, as the tension on its cables produced by pulling the mine-cars tends to move it backward. Anchor-clamps 72, projecting rearward ly from the truck, are provided. The clamp comprises a strut-bar 73, having an elongated slot 74 at one end. A rail-engaging foot 75, having downwardlyextending lateral flanges 76 77, extends from the other end at an angle to the body of the bar. There is a fixed collar 78 intermediate the ends of the bar. Supported on the strutbar above the collar are hooks 79 80, having eyes surrounding the bar and adapted to engage beneath the flange of the rail, as shown in Figs. 5 and 6. At its upper end the strutbar is connected to the truck by means of a pin 81, passing through the slot 74 and supported in the downwardly-extending portions of L-shaped plates 82 83, bolted to the truck. This anchor-clamp when in position on the rail is automatic in its action. hen the truck moves forward, the strut-bar is permitted to assume a sharper angle with the track, and the hooks are released fromengagement with the flange; but upon rearward movement of the truck, due to friction of the foot upon the track, the hooks engage the flanges of the rails, the rail is clamped, and further rearward movement stopped. The anchor-clamp may be disengaged from the rail by swinging the hooks outwardly from the rail, the eyes being large enough to permit this motion.

To support the anchor-clamp when out of use, a projecting plate 84 and hook 85 are mounted upon the truck. The slot 74 permits longitudinal movement of the strut-bar 73 to bring the end thereof beneath the plate, as shown in dotted lines in Fig. 5. The foot of the strut-bar is provided with an eye 86, which is engaged by the hook 85.

The mechanism has been shown mounted upon a truck. A loading-machine may be conveniently mounted upon the same truck. A shaft 87 may be connected with the loading-machine, and thus the latter may be driven from the same motor that drives the mechanism hereinbefore described.

In operation the drums may be thrown out of gear with the secondary bevel-gears by means of the shifting-lever 60. Then the clutch member 34 may be thrown into engagement with either of the secondary bevelgears by means of the shifting-lever 39, and the truck may be propelled forward or backward, as may be desired. hen the machine has been brought to the desired position, the

, anchor-clamps may be released from the hooks 85 and allowed to clamp the track-rail. Then the clutch member 34 may be released from its engagement with the secondary bevel-gear. To bring up a car, the drum 47 is thrown into gear with the secondary bevel-gear 25. The cable will then be wound up on the drum 47 and will be paid out from the drum 46. 1f the latter reels off too rapidly, its speed can be controlled by means of the brake. To remove the car, the shifting-lever 60 is operated, and. the drum 47 is thrown into gear with the secondary bevel-gear 24, and the drum 46 is thrown out of gear with its secondary bevelgear. The cable will now be wound up on the drum 47 and paid out from the drum 46.

hen it is desired to move the car-puller farther into the mine-chamber, it is only necessary to throw both winding-drums out of gear and the clutch member 34 into gear. Then as the machine moves forward the required additional length of cable will be paid out from both drums. The machine is thus ready for operation as soon as it reaches its new position, and it is unnecessary to change any of the cable connections.

Obviously the machine admits of considerable modification within the scope of my invention,'and therefore I do not wish to be limited to the specific construction shown and described.
